What is the EGR valve on a Mazda 6?
They are the EGR Valve, Differential Pressure Sensor, and the Actuator Solenoid. P0401 is a general code, which means that regardless of the year (1996+ anyway) and the model, it’ll have the same meaning regardless of which manufacturer built the vehicle (Mazda 6 or not).
What are the parts of the EGR system?
The EGR system on a vehicle is responsible for recirculating exhaust gasses in order to lower the vehicles emissions output. There are three main parts of the 6’s EGR system. They are the EGR Valve, Differential Pressure Sensor, and the Actuator Solenoid.
How to test the EGR valve on a Jeep Wrangler?
Test the EGR Valve- A vacuum gauge will help you determine if the EGR valve itself has gone bad. Here’s an article from Autozone on how to test it with a vacuum gauge. Testing your EGR system is relatively easy to do. The most challenging aspect is the DPFE sensor.
Why is my EGR not working on my Acura MDX?
Vacuum Issues – The EGR valve relies on engine vacuum to operate. So, if you are encountering P0401 and other codes, the P0401 may be a symptom of larger problems. For instance, if the motor is not running well enough to create sufficient vacuum to operate the EGR valve, than P0401 will often be thrown.

What to do if your Mazda 6 p0401 has insufficient flow?
Check the EGR Tube- It’s a good idea to check the tube going to the EGR because it’s often the cause of P0401, easy to do, fast, and replacing it is very afMazdaable. If it’s cracked, you’ll need to get a new one. If it’s clogged you can get away with cleaning it and replacing it.
